Ehis rocks the crossbar 102, cousin a ten- \sion in the chains 101 and 103 an a consequent shorteningin the continuous connectinn, made up of the said cross-bars and intermediate chain connections, takes place which draws all members inwardly, resulting in a binding action between the curved. portions of said members and the tread of gr-ally with the said wheel "56, giving firmness to the member 86, whereby a po nt of concentrated pressure 13 located 1n a fixed slipping of the same on the road. The shifting action circumferentiall upon the tire in this case may take place under the circumstances described for the form of deillustrated in Fig.1, in connection with the members.

Having described my inventioml claim .1. In a' non-slipping traction device for rality of members positioned transverse to and-in contact with the tire of said 'wheel, of chain connections j'ournaled on iiiner portions of said members in continuous con-' 40 nection, each of said members having a a bar or lever portion positioned bet-ween the tire of said wheel anc'Lthe hub of the same, said chain connections being journaled to join a point near the inner end of said bar portion of one member with the bar portio'n of a neighborimi memberat a point away from theend of the same, and all neighboring members being similarly connected.

2.- In a non-slipping traction device for vehicle wheels, the combination with a plurality of members positioned transverse to and in contact with the tire of said wheel, of chain connections journaled on the inner portions of said members in continuous con nection, each of said members having a.

concentrated pressure at the said point of the tire finds suflicient friction thereon, the

operation, referring to Fig. fi,the memhe ire 77 and makes the device act into "position on said tire 77 and prevents the.

vehicle wheels, the combination with spin curved portion in contact with said tire, and

curved portion in contact with said tire,

tire concentric with the same and having pivoted thereto each of said members substantially as set forth.

A device of the class described, comprising the combination of a plurality-of like. members,- spaced cireumferentlally.

about the tire'ofa vehicle wheel and transeach an inverse to said'tire and havin wardly positioned bar extension, chainlike connections continuously joining the said bar extensions and a ring ositioned near said tire and having pivotec thereto each of the said members.

i. A non-slipping traction device-,- adaptcdto be mounted upon a vehicle wheel, com.- prising a plurality of' similar members spaced circumferentially about the tire of said wheel and transverse to said tire, each of saidmembers having an inwardl positioned bar extension, means connectlng the inner ends of neighboring bar extensions,

said means being journaled at two separate.

.points upon each of said inner ends, and a ring positioned near said tire and having pivoted thereto each of said members, substantially as set forth.

5. Anon-slipping traction device, adapted to be mounted upon the tire of a vehicle wheel, comprising a plurality of members spaced circumferentially upon and transverse'to the tractive surface of said tire, each member having a lever portion extend.- ing toward the hub of said wheel, the normal longitudinal direction of said lever por tion being inclined to a radius of said wheel passing through the central point of contact of the member, of which said lever portion is a part, and the said tire, said lever portions being linked together for their coaction in a manner to produce a gripping of said ,tractive surface by, said device, when one of said lever portions is tilted by the retau-ding action of its member with the ground.
